This record describes the Conductivity-Temperature-Depth (CTD) data collected from the Marine National Facility RV Investigator voyage IN2015_C01, titled: "Great Australian Bight (GAB) deep water geological and benthic ecology program". The voyage took place from Hobart (TAS) to Port Lincoln (SA) between October 22 and November 28, 2015.
Data for 16 deployments were acquired using the Sea-Bird SBE911 CTD 20, fitted with 36 twelve litre bottles on the rosette sampler. CSIRO-supplied calibration factors were used to compute the pressures and preliminary conductivity values. CSIRO-supplied calibrations were applied to the temperature data. The data were subjected to automated QC to remove spikes and out-of-range values.
Cast 1 was a test down to 100m. Deployment 4 was aborted early due to winch issues. Deployment 7 was a test cast to examine winch issues. Data Spikes in casts 8 and 9 were likely due to the LISST particle size sensor which was attached to the CTD serial port for casts 7-9. A Rinko Oxygen sensor was used for casts 1-7, 10-15.
A Chelsea turbidity, PAH, chlorophyll, and CDOM sensors, the Biospherical PAR sensor, Rinko III oxygen sensor, Franatech methane sensor, and a Tritech altimeter were also fitted on the auxiliary A/D channels of the CTD.
The collected data were subsequently processed and archived within the CSIRO Oceans and Atmosphere (O&A) Information and Data Centre (IDC) in Hobart. Additional information regarding this dataset may be contained in the Voyage Summary and the CTD Data Processing Report.
